Description

Technical Field

[0001] This application relates to the field of electric luggage technology, and in particular to an electric luggage with a fastening cover. Background Technology

[0002] As people's living standards improve and consumption concepts change, consumers have higher requirements for the convenience, safety, and comfort of travel products. Electric suitcases not only meet basic storage needs but also enable autonomous movement through electric drive. Some models also feature functions such as hill-climbing assistance and load-bearing support, catering to consumers' pursuit of high-quality travel.

[0003] The core requirement of electric suitcases is to carry luggage. They typically have storage cavities inside and an openable lid on the outside for storing and carrying luggage. However, the connection between the lid and the suitcase is not stable. Due to the need for frequent opening and closing, zippers or buckles are usually used to directly and detachably connect the lid to the suitcase. Even when locked, the lid of most electric suitcases still wobbles. The lid and the suitcase can only be supported by the zipper or buckle connection, which significantly reduces the load-bearing capacity of the sides of the suitcase. If heavy objects such as backpacks or handbags are placed on top of the lid, it may cause the lid to deform or the connection between the lid and the suitcase to be damaged, thus affecting the overall usability of the suitcase.

[0004] To address the aforementioned technical problems, Chinese patent document CN210581348U discloses an electric suitcase, including a suitcase body, a drive wheel located below the suitcase body, and a power source for providing electricity. The suitcase body includes a first part and a second part that can be opened and closed relative to the first part. The first part forms an outwardly opening receiving cavity, and the second part can cover the opening to close the receiving cavity. A reinforcing member is installed inside the receiving cavity. The reinforcing member has a contact surface that abuts against the inner wall of the receiving cavity and a reinforcing surface opposite to the contact surface. Reinforcing ribs are provided on the reinforcing surface. While the above patent includes a reinforcing member inside the receiving cavity of the first part, it does not reinforce the connection between the outer cover and the suitcase body. Bumps during riding cause the outer cover to repeatedly collide with the edge of the suitcase body, making the outer cover prone to loosening over time. The unstable outer cover also results in asymmetrical storage cavities inside the suitcase, leading to uneven lateral force during riding, further affecting the lifespan of the outer cover and causing the suitcase to veer or tilt during gliding, affecting the smoothness of use.

[0005] Therefore, it is necessary for those skilled in the art to provide an electric suitcase with a fastening cover, so that the outer cover can be firmly connected to the suitcase body during use, preventing shaking and improving the service life and stability of the electric suitcase. Summary of the Invention

[0006] The purpose of this application is to provide an electric suitcase with a fastening cover to solve the technical problems in the prior art where the frequently opened and closed outer cover of the electric suitcase is easy to shake, and the structural strength of the connection between the outer cover and the suitcase body is low and easily damaged.

[0007] The technical solution adopted by this application to solve its technical problem is as follows: an electric suitcase with a fastening cover, including a suitcase body, a storage cavity formed inside the suitcase body, and an outer cover that can be opened and closed outside the suitcase body. A connecting frame is provided between the suitcase body and the outer cover. The connecting frame is fixedly connected to the suitcase body, and the outer cover is detachably installed on the connecting frame. A mating part is provided on the inner ring wall of the connecting frame, and a plug-in part is formed on the outer cover. The plug-in part can be plugged into the mating part. A fastening component is provided between the connecting frame and the outer cover. The fastening component is arranged around the inner contour of the connecting frame. The fastening component includes a first airbag, a second airbag, and an inflation pump for connecting the first airbag and the second airbag. The inflation pump can supply air to the first airbag and the second airbag. The first airbag and the second airbag are arranged in the mating part, and the first airbag and the second airbag can abut against the plug-in part.

[0008] Furthermore, the mating part has an overall square frame structure, and the cross-section of the mating part is U-shaped. The mating part includes a first wall, a second wall, and a mating gap located between the first wall and the second wall. The first airbag is installed in the first wall and the first airbag portion can extend into the mating gap. The second airbag is installed in the second wall and the second airbag portion can extend into the mating gap.

[0009] Furthermore, the plug-in portion on the outer cover is plugged into the mating gap, and the first airbag and the second airbag are located on both sides of the plug-in portion and can abut against the plug-in portion.

[0010] Furthermore, grooves are formed on the surfaces of the first and second walls facing the mating gap, and the first and second airbags are both mated and connected in the grooves.

[0011] Furthermore, the groove surrounds the inner ring contour of the connecting frame, and the groove is opened from the mating gap into the wall of the mating part. The groove is an eccentric arc-shaped groove, and the width of the opening surface of the groove is smaller than the diameter of the groove.

[0012] Furthermore, there is one first airbag and two second airbags. The surface of the insertion part facing the first airbag has a first arc surface, and the surface of the insertion part facing the second airbag has a second arc surface. The first arc surface and the second arc surface are staggered, and the corresponding first airbag and second airbag are also staggered.

[0013] Furthermore, the air pump is located at the bottom of the outer cover, and the air outlet of the air pump is provided with a first connecting valve and a second connecting valve. The first connecting valve is connected to the first airbag, and the second connecting valve is connected to the second airbag. The first connecting valve and the second connecting valve are two-way valves.

[0014] Furthermore, a connector is provided between the outer cover and the connecting frame, and the outer cover is rotatably mounted on the connecting frame through the connector; the connector includes a first fixing seat fixedly connected to the bottom of the outer cover and a second fixing seat fixedly connected to the bottom of the mating part, the second fixing seat is rotatably provided with a rotating seat, the end of the rotating seat is provided with a sliding seat, and the first fixing seat is slidably fitted into the sliding seat.

[0015] Furthermore, the sliding seat is provided with a sliding part, and the first fixed seat is provided with a mounting part. The mounting part is snapped into the sliding part and can be slidably disposed along the extension direction of the sliding part.

[0016] The beneficial effects of this application are as follows: By setting a U-shaped mating part, the plug-in part is plugged into the mating part and then pushed back by multiple airbags, thereby reducing the contact between the plug-in part and the mating part, preventing it from shaking, reducing collisions and friction between the two during movement, and thus improving the stability of use. At the same time, this application presses the first airbag in one direction and the two second airbags press in opposite directions, improving the local fit and preventing it from coming out of the mating gap or shaking, further reducing the friction between the plug-in part and the mating part; the staggered arrangement of the first and second airbags allows the pressure on the plug-in part to be distributed more evenly, thereby preventing the plug-in part from extending too far into the mating gap, reducing jamming and deformation, and ensuring the stability of the electric luggage in various usage conditions.

[0030] The present application will now be described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present application, and therefore only show the components relevant to the present application.

[0031] Please see Figure 1 , Figure 2 This application provides an electric suitcase with a fastening cover, including a suitcase body 10, a storage cavity 12 formed inside the suitcase body 10, an outer cover 11 that can be opened and closed outside the suitcase body 10, a connecting frame 13 between the suitcase body 10 and the outer cover 11, the connecting frame 13 being fixedly connected to the suitcase body 10 by fasteners such as rivets, a connector 30 being provided between the outer cover 11 and the connecting frame 13, the outer cover 11 being rotatably mounted on the connecting frame 13 by means of the connector 30.

[0032] A fastening component 20 is provided between the connecting frame 13 and the outer cover 11. The fastening component 20 is arranged around the inner contour of the connecting frame 13. The fastening component 20 is used to tightly connect the outer cover 11 to the connecting frame 13, thereby ensuring that the outer cover 11 can be stably connected to the electric luggage box after being closed, preventing shaking.

[0033] Understandably, the electric luggage box described in this application also includes components such as a steering handle, a telescopic motor, and a battery. For details on the specific structure, please refer to the novel electric luggage box disclosed in Chinese Invention Patent CN202211162539.8, which will not be elaborated here.

[0034] Please see Figures 3-6 The fastening assembly 20 includes a first airbag 21, a second airbag 22, and an inflation pump 23 for connecting the first airbag 21 and the second airbag 22. The inflation pump 23 can inflate the first airbag 21 and the second airbag 22, and the inflation pump 23 is electrically connected to the battery of the electric luggage compartment (not shown).

[0035] The connecting frame 13 has a ring-shaped structure, and a mating part 14 is provided on the inner ring wall of the connecting frame 13. A plug-in part 15 is formed on the outer cover 11, and the plug-in part 15 can be plugged into the mating part 14 on the connecting frame 13. At the same time, the first airbag 21 and the second airbag 22 are disposed in the mating part 14, and the first airbag 21 and the second airbag 22 can abut against the plug-in part 15.

[0036] In use, the outer cover 11 is installed onto the housing 10, and the plug-in part 15 on the outer cover 11 is plugged into the mating part 14 on the connecting frame 13 to achieve closure. Then, the air pump 23 is started to inflate the first airbag 21 and the second airbag 22, causing the first airbag 21 and the second airbag 22 to expand and abut against the plug-in part 15, thereby making the plug-in part 15 tightly connected to the mating part 14. This ensures that the outer cover 11 is tightly connected to the housing 10, preventing it from shaking, reducing collisions and friction between the two during movement, and thus improving the stability of use.

[0037] Specifically, the mating part 14 has a square frame structure with a U-shaped cross-section. The mating part 14 includes a first wall 141, a second wall 142, and a mating gap 143 between the first wall 141 and the second wall 142. The first airbag 21 is installed inside the first wall 141, with a portion extending into the mating gap 143. The second airbag 22 is installed inside the second wall 142, with a portion extending into the mating gap 143. Simultaneously, the insertion / removal part 15 on the outer cover 11 is inserted / removed into the mating gap 143. The first airbag 21 and the second airbag 22 are located on either side of the insertion / removal part 15 and can abut against it. This achieves a tight fit against the insertion / removal part 15.

[0038] In this embodiment, the first wall 141 and the second wall 142 are provided with grooves 144 on their surfaces facing the mating gap 143. The first airbag 21 and the second airbag 22 are both mated and connected in the grooves 144, thereby realizing the installation and fixation of the first airbag 21 and the second airbag 22. In the deflated state, the first airbag 21 and the second airbag 22 retract into the grooves 144. In the inflated state, the first airbag 21 and the second airbag 22 partially extend into the mating gap 143, thereby pressing the insertion part 15.

[0039] The groove 144 surrounds the inner ring contour of the connecting frame 13. The groove 144 extends from the mating gap 143 into the wall of the mating part 14. The groove 144 is an eccentric arc-shaped groove, and the width of the opening surface of the groove 144 is smaller than its diameter; that is, the diameter of the groove 144 is located within the wall of the mating part 14. This ensures that the first airbag 21 and the second airbag 22 can be stably placed within the groove 144 and will not detach even when deflated, improving operational stability. Simultaneously, if the first airbag 21 or the second airbag 22 is damaged or leaks, it is easy to remove and repair, extending its service life.

[0040] In this embodiment, the outer cover 11 is made of plastic, and the outer cover 11 and the plug-in part 15 are integrally formed to ensure structural strength.

[0041] In this embodiment, there is one first airbag 21 and two second airbags 22. The insertion / extraction part 15 has a first arc surface 151 facing the first airbag 21 and a second arc surface 152 facing the second airbag 22. The first arc surface 151 and the second arc surface 152 are staggered, and the corresponding first airbag 21 and second airbag 22 are also staggered, thus making the compression of the insertion / extraction part 15 more accurate and stable. Since the insertion / extraction part 15 is inserted and pulled into the mating part 14, and the mating part 14 has a frame structure, the displacement direction of the outer cover 11 is limited. After prolonged use, some walls of the insertion / extraction part 15 will wear against the mating part 14, causing the gap to widen, resulting in loosening and shaking. Alternatively, when the outer cover 11 is subjected to pressure, the insertion / extraction part 15 may extend excessively into the mating part 14 and deform, causing the insertion / extraction part 15 to become stuck inside the mating part 14.

[0042] Therefore, this application presses the first airbag 21 in one direction and the two second airbags 22 press in opposite directions (alternating directions), so that the plug-in part 15 forms a "locked state" within the mating gap 143, which can improve the local fit and prevent it from coming out of the mating gap 143 or shaking, thereby reducing the friction between the plug-in part 15 and the mating part 14. Since the plastic plug-in part 15 is relatively weak, the staggered arrangement of the first airbag 21 and the second airbag 22 makes the pressure on the plug-in part 15 more dispersed. When the outer cover 11 is subjected to external force, the first airbag 21 and the second airbag 22 will bear part of the pressure to achieve buffering, thereby preventing the plug-in part 15 from extending excessively into the mating gap 143, reducing jamming and deformation, while improving the load-bearing capacity of the side of the box 10, preventing damage to the connection between the box 10 and the outer cover 11, and ensuring the stability of the electric suitcase under various usage conditions.

[0043] In other embodiments, there is one first airbag 21 and two second airbags 22, with the first airbag 21 located between the two airbags 22, thus forming a "triangular force-bearing structure". This provides stronger coverage for the insertion part 15, can counteract the slight deformation of the insertion part 15 caused by temperature changes or squeezing and shaking, and maintain the stability of the outer cover 11 in use.

[0044] Please see Figure 3 , Figure 6 The air pump 23 is located at the bottom of the outer cover 11. The air outlet of the air pump 23 is provided with a first connecting valve 24 and a second connecting valve 25. The first connecting valve 24 is connected to the first airbag 21, and the second connecting valve 25 is connected to the second airbag 22. The first connecting valve 24 and the second connecting valve 25 are bidirectional valves, used to inflate and deflate the first airbag 21 and the second airbag 22.

[0045] The air pump 23 is a common small electric air pump for inflation and deflation on the market, and its specific structure will not be described in detail.

[0046] Please see Figures 7-12 The connector 30 includes a first fixing seat 31 fixedly connected to the bottom of the outer cover 11 and a second fixing seat 32 fixedly connected to the bottom of the mating part 14. A rotating seat 33 is rotatably provided on the second fixing seat 32. One end of the rotating seat 33 is rotatably connected to the second fixing seat 32 by a rotating shaft. A sliding seat 34 is provided at the other end of the rotating seat 33. The first fixing seat 31 is slidably fitted into the sliding seat 34.

[0047] Furthermore, the sliding seat 34 is provided with a sliding portion 35, and the first fixed seat 31 is provided with a mounting portion 36. The mounting portion 36 is snapped into the sliding portion 35 and can slide along the extending direction of the sliding portion 35. This allows the first fixed seat 31 to slide relative to the sliding seat 34, thereby ensuring that the insertion / removal portion 15 can be stably inserted / removed into the mating portion 14.

[0048] To achieve double-sided pushing of the insertion part 15 on the outer cover 11 and prevent wear, this application provides a U-shaped mating part 14. The insertion part 15 is inserted into the mating part 14, and then pushed by multiple airbags, thereby reducing contact between the insertion part 15 and the mating part 14. However, to ensure the stability of the airbag pushing, the insertion part 15 has a certain stroke when inserted into the mating part 14, which can cause some interference when the outer cover 11 is directly rotated open and closed. Therefore, this application provides a first fixing seat 31 and a mounting part 36 on the outer cover 11. The first fixing seat 31 is slidably mounted on a sliding seat 34, allowing the outer cover 11 to slide relative to the housing 10 by a certain distance. This allows the insertion part 15 to smoothly move out of the mating part 14 before rotation, ensuring the stability of the opening and closing of the outer cover 11.

[0049] In use, rotate the outer cover 11 to merge the rotating seat 33 onto the second fixed seat 32. Move the outer cover 11, and the mounting part 36 moves along the sliding part 35. The insertion part 15 is inserted into the mating part 14, thereby inserting the outer cover 11 into the housing 10. Start the air pump 23, and the first airbag 21 and the second airbag 22 inflate and compress both sides of the insertion part 15 to secure the outer cover 11. When opening the outer cover 11, start the air pump 23 to release the gas in the first airbag 21 and the second airbag 22, move the outer cover 11 outward, disengage the insertion part 15 from the mating part 14, and then rotate the outer cover 11 to open and close it.

[0050] In this embodiment, the mounting part 36 is a dovetail tenon, and the sliding part 35 is a dovetail groove. The dovetail tenon is adapted to be connected in the dovetail groove, thereby ensuring the stability of the connection and sliding and preventing it from coming off.

[0051] In other embodiments, the mounting part 36 is a roller, the sliding part 35 is a groove, the roller is slidably disposed in the groove and can slide along the opening direction of the groove, thereby ensuring the smoothness and stability of the movement of the outer cover 11.

[0052] In this embodiment, a combination lock is provided at the end of the case 10 away from the connector 30, and a locking tongue is provided on the outer cover 11. The locking tongue can be plugged into the combination lock to lock the outer cover 11 and prevent the outer cover 11 from falling out, thereby improving the stability of use. The combination lock is a common combination lock for bags on the market, and its specific structure will not be described in detail here.

[0053] In other embodiments, the connector 30 is made of soft plastic. One end of the connector 30 is fixedly connected to the bottom of the outer cover 11, and the other end of the connector 30 is fixedly connected to the bottom of the mating part 14, thereby ensuring that the outer cover 11 is connected to the box body 10 and reducing production costs.

[0054] This application utilizes a U-shaped mating section 14, where the plug-in part 15 is plugged into and pulled into the mating section 14. Multiple airbags then push against it, reducing contact between the plug-in part 15 and the mating section 14, preventing wobbling, and minimizing collisions and friction during movement, thus improving stability. Simultaneously, the application directs the pressure of the first airbag 21 in one direction and the pressure of the two second airbags 22 in opposite directions, enhancing local fit and preventing the plug-in part 15 from slipping out of the mating gap 143 or wobbling, further reducing friction between the plug-in part 15 and the mating section 14. The staggered arrangement of the airbags further distributes the pressure on the plug-in part 15, preventing it from overextending into the mating gap 143, reducing jamming and deformation, and ensuring the stability of the electric luggage under various usage conditions.

[0055] It is understood that this application has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this application. Furthermore, based on the teachings of this application, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this application. Therefore, this application is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this application.
